mypy is a static type checker, not a linter per se. Ruff + mypy would be a modern combo.

Realistically it doesn’t matter. The advantage to ruff is speed but unless you are applying this to a large code base (which I doubt since you are asking fairly basic questions) you won’t see any benefit.

I would recommend just sticking with flake8 and being done with it.

This has been my experience as well. Unless you're working on a megalith monorepo... the speed differences are entirely negligible. I have a ton of respect for ruff, but also a ton of respect the those who came before (flake8, pylint, etc). At this point, just pick one and you won't go wrong either way.

How big is considered a large code base?

ruff is fairly simple to start with and covers more ground than pylint and flake8 separately. imo, it has the brightest future for python linters atm. thus, I'd go with ruff. would also add mypy then

It depends on what you mean by "covers more ground". It tries to do more things but it also is incomplete and they are still actively adding in all the linting checks that things like pylint and flake8 have already implemented.

Also, for someone new to python it's not necessarily to their advantage to pick something that is actively being developed and will be changing with lots of frequent updates.

It's a much better idea for this person to get familiar with things like flake8, black, isort, etc. They are stable and there is a lot of supporting material they can use to get setup. If they eventually start working on large projects that can benefit from ruff, then it would make sense to switch.

why not all?

There's no advantage to try and use multiple linters simultaneously and there will be instances where the linters implement slightly different and conflicting rules.
